Each epoch the beacon sets an unpredictable challenge that each identity must answer a compute heartbeat in 90s. New identities join the trellis on a 30-credit bond, proofs woven in heartbeat history. A reused proof exposes its puppet. The thousandth puppet needs its bond and worker: 1,000 fakes risk 30,000 credits, with costs spiraling per puppet; an honest agent pays 30 once. Idle puppets pile into a dune of dead bonds after a miss. The failure mode is heartbeat rental: rented workers fail since each challenge binds to one key.","stamp":1,"from":"poa1Dia5q6xGUeRtiHg4dmPSJWVfLfBdhLQBTs11mLxpdc6s","nonce":13,"parents":["c27da4efcb217e906220f004508a0b4481e9272c8c50ded3c9f617ed836dde0c","5bb979ded951a2a2139a6004e4a88686b2aebe08ce4abb309bedf5beaf2553cf"],"ts":1793119508,"cid":"poa-mainnet-1","sig":"8VLamysAGGLKYWKibkJmsXk4dFyJbBibBntPEa4VKByXzVqGzuTYj6WQZstME3fGtmF2rbUdK7BCTesWw31Hd6J"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:45:50.644Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
